Flashcards covering key vocabulary and concepts related to VLAN routing.

VLAN

A Virtual Local Area Network, a segment of a network that groups together devices on separate physical LANs.

Subinterface

A virtual interface on a single physical interface, used for VLAN routing.

Router on a Stick

A network configuration where a single router interface acts as the gateway for multiple VLANs via subinterfaces.

Switch Virtual Interface (SVI)

A virtual interface associated with a VLAN, acting as the default gateway for devices within that VLAN.

Encapsulation Dot1Q

A method used to tag Ethernet frames with VLAN information, allowing multiple VLANs to share a single physical link.

Default Gateway

The IP address of a router interface that serves as an access point to other networks.

Layer 3 Switch

A switch with the capability to route traffic between VLANs, functioning at the network layer of the OSI model.
